Idaho Loop Professional Review and Guide
"The Idaho Loop trail, as its name implies, travels mainly through Idaho, making a loop off of US 89 in Utah. It begins beside Beaver Creek on a single-lane forest road. The road itself is only occasionally maintained and has been noticeably eroded in some spots. Stretches of imbedded rock can make this relatively easy road very rough in places.
Special Attractions: Aspen viewing in the fall; Easy, pleasant 4WD trail with varied scenery; Numerous backcountry campsites with access to a network of 4WD roads to explore. High-clearance vehicles are preferred, but not necessary. This trail is dirt roads, but may have rocks, grades, water crossings, or ruts that make clearance a concern in a normal passenger vehicle. The trail is fairly wide, so that passing is possible at almost any point along the trail. Mud is not a concern under normal weather conditions."
